Prioritizing government spending.

[Tellos Athenaios]

A point is that if you talk about your basic infrastructure: the rich tend to use, quite literally, more of it. (More water, more electricity, more tarmac, more real estate.)
And before you say “but I thought I paid the water/electricity/gas company a monthly fee” consider that often enough not all costs are amortized and charged to the customer in that fashion. (The running cost of power grids is amortized per customer; not per watt AFAIK.)
